New Revision: 27257
   Changeset: http://svn.mythtv.org/trac/changeset/27257

Log:

Refs #9150. Reduces I/O priority of background video processing tasks, mythcommflag (when not run with --cpuhog) in particular. This allows MythTV to behave better with the CFQ I/O scheduler. The CFQ I/O Scheduler isn't ideal for the MythTV use case, but it is the Linux default so we should try our best to work well with it.
